No ... that's not a typo. It's a reference to a semi-recently-developed touristy sort of thing in major cities which might best be described as an 'all-nighter'. More and more cities are getting into this sort of thing and the New York Times has a run down of what's going on where around the world. Inter alia, in regards to Rome we read:

Rome (www.lanottebianca.it) is trying to capitalize on the all-night party’s potential tourism draw by planning a full program of events for the weekend. These include a concert by the Italian pop icon Lucio Dalla at the Villa Borghese and a reading from “The Aeneid” — in Italian — on the Piazza del Campidoglio (City Hall) on Friday evening, Sept. 7, as a sort of curtain raiser.

... I think that's the first press mention of an epic reading in a language other than the original or English ...
